Multilib version problems found. This often means that the root

       cause is something else and multilib version checking is just

       pointing out that there is a problem. Eg.:

         1. You have an upgrade for zlib which is missing some

            dependency that another package requires. Yum is trying to

            solve this by installing an older version of zlib of the

            different architecture. If you exclude the bad architecture

            yum will tell you what the root cause is (which package

            requires what). You can try redoing the upgrade with

            --exclude zlib.otherarch ... this should give you an error

            message showing the root cause of the problem.

         2. You have multiple architectures of zlib installed, but

            yum can only see an upgrade for one of those architectures.

            If you don't want/need both architectures anymore then you

            can remove the one with the missing update and everything

            will work.

         3. You have duplicate versions of zlib installed already.

            You can use "yum check" to get yum show these errors.

       ...you can also use --setopt=protected_multilib=false to remove

       this checking, however this is almost never the correct thing to

       do as something else is very likely to go wrong (often causing

       much more problems).

       Protected multilib versions: zlib-1.2.7-19.el7_9.x86_64 != zlib-1.2.7-18.el7.i686
